I would look into the Roush and the ATI Procharger.
I also have been eying that Roush Kit although i have the Procharger on my truck and really like it. I would also suggest you look into the Whipple Kit.

Any of the screw type supercharges will give you lots more power down low and feel much more like more displacement then the centrificial blowers. Makes it more streetable provided you don't experience traction problems.

Leroy,
I just installed a Vortech and aftercooler on my car and running the oil lines were not a big deal at all. The supply runs off a t-fitting where the stock oil pressure sending unit is (near old filter) and the return line is also a easy install that is tapped into the oil pan. Neither were hard to run or install. Piece of cake. What ever you decide to go with, I am sure you will like it. I sure do.
